Self-expandable stainless steel braided endoprosthesis for biliary strictures.
A new type of biliary stent was inserted in 45 patients with symptomatic biliary strictures, 40 malignant and five benign. The stent is made of stainless steel woven into a tubular mesh. It is introduced in compressed form on a 7- or 9-F delivery catheter and released at the site of the stricture. Fully open, the stent has an internal diameter of 1 cm. The 30-day mortality was 7%. The early (less than 72 hours) complication rate was 16%. Recurrent jaundice occurred in 42%; late complications of sepsis without jaundice occurred in an additional 11%. None of the stents migrated. This new design allows a large-diameter stent to be inserted percutaneously without increased risk of complications. The frequency of recurrent jaundice, however, was not less than that observed with plastic stents, but this may have reflected the spectrum of patients treated, many with hilar strictures and previous interventions.
